author list wrong

[Xunius]

There is a mistake that when a field fetched is a sequence (e.g. author list), the sequence length can be wrong when there are duplicates.

E.g.

firstnames = L.Y., M.C., Y.L., Y.C., F.H.
lastnames = Oey, Chang, Chang, Lin, Xu

Because the duplicate (Chang) in the lastnames list is removed, the resultant author list ends up as:

Oey, L. Y. and Chang, M. C. and Lin, Y. L. and Xu, Y. C.

A fix is coming soon
